However, should this resistance not be present, for example during periods of low load or downtime, it is possible that dryers and filters may be "overwhelmed" by the sudden surge in airflow that occurs when the system re-starts. DHS air-main charging systems reliably prevent this from occurring.

The installation of a Kaeser DHS air-main charging system guarantees the required minimum pressure and ensures reliable operation, and in particular when re-starting the system following a shut-down.Gentle pressure build-up in the system:A pulse width modulated control designed by Kaeser ensures that system intervention opening and closing sequences are performed in very small steps.A brilliantly simple operating concept:Easy configuration in 25 languages, immediate recognition of the operating state, manual emergency-stop - time-saving features that also increase safety. Kaeser Life Cycle Management Kaeser Life Cycle Management Even the best components are only as good as their integration into the overall system. With Kaeser, you benefit from individual consultation and intelligent technology that can be used universally and expanded as required.

This prevents damage and increases the effectiveness of air treatment equipment. It also pressurizes the entire air system in the shortest possible time.Why your system needs a DHS charging valveCompressed air dryers and filters are designed and rated to treat specified volumes of air at specific conditions. A refrigerated dryer, for example, is rated to achieve a specified dew point at a particular volume (scfm), pressure (100 psig), compressed air temperature (100 ºF), and ambient temperature (100 ºF).If system pressure is not constant, the air velocity through clean air treatment equipment will fluctuate. For those operating 24 hours a day, fluctuation may be minor. If, however, compressors are shut down for any length of time (overnight, weekends, holidays), system pressure will drop significantly as air escapes through leaks. Until full, or near full, operating pressure is reached, dryers and filters may not work to specification and contaminants may be swept downstream.Air quality protectionAn air main charging valve controls high velocity air while an air system is being pressurized. After the air system has been pressurized, the air main charging valve also prevents exposure of air treatment components to possible overflow conditions. Leaks, artificial demand, and unregulated uses all affect the total demand for air. When this total demand reduces the system pressure, the increased air velocity may greatly reduce the effectiveness of air treatment components. A DHS charging valve prevents this condition, ensuring that dryers and filters will be able to operate according to their rated specifications.
